Plastic v galvenised Rain water tanks

[kellwin]

I want to get 2 x 9000ltr tanks to hook up to the house for domestic use as part of the reno. Anyone have a feel have had experiences for which type type of rain water tank is better? Plastic or galv?
Have heard that plastic can crack after time and the ones made out of china can be suspect. From what I have read warranties are about the same length. Only problem with galv I can see is rusting after time. Both affect taste? Will be filtered before drinking anyway.

I would be looking at Fiberglass sectional tanks.
